Recently, Gasimov and Yenilmez proposed an approach for solving two kinds of fuzzy linear programming (FLP) problems. Through the approach, each FLP problem is first defuzzified into an equivalent crisp problem which is non-linear and even non-convex. Then, the crisp problem is solved by the use of the modified subgradient method. In this paper we will have another look at the earlier defuzzifi...

In a transparent optical network, a transmitted signal remains in the optical domain over the entire route (lightpath) assigned to it between its source and destination nodes. In this paper, a novel Fuzzy dynamic routing and wavelength assignment technique is proposed for a wavelength division multiplexing (WDM) optical network, to achieve the best quality of network transmission and network se...

The paper introduces an alternative approach to time-series prediction for stock index data using Interval Type-2 Fuzzy Sets. The work differs from the existing research on time-series prediction by the following counts. First, partitions of the time-series, obtained by fragmenting its valuation space over disjoint equal sized intervals, are represented by Interval Type-2 Fuzzy Sets (or Type-1 ...

Using fuzzy sets for reasoning is what we mean when talk about logic. Contradictory natures are prevalent phenomena in the medical field. Guidelines used by anesthesiologists taking care of patients. After gauging patient’s vitals, he may make adjustments to flow medication and fluids, or even ventilator settings. Knowledge real world typically sketchy, inaccurate, inconsistent. Due inherent re...

Abstract This paper describes the research procedures adopted in developing a triangular fuzzy number scale based on semantic of MACBETH (Measuring Attractiveness by Categorical Based Evaluation Technique). The objective was to mathematically treat uncertainty and subjectivity linguistic variables used assess decision problem. A matrix initially obtained maker’s assessment given context analysi...
